Matt Barnes traded to Marlins from Boston (source)

The Marlins added an experienced late-inning option to their bullpen on Monday afternoon by acquiring Matt Barnes and cash considerations from the Red Sox for left-hander Richard Bleier, a source told MLB.com on Monday.

The club did not confirm the news.

The longest-tenured Red Sox player until they designated him for assignment on Tuesday, Barnes had become one of the club’s most trusted relievers by 2016. During the ‘18 World Series championship run, he dominated across 10 playoff appearances.

Barnes became the full-time closer in 2021, recording a 124 ERA+, a 1.12 WHIP and 24 saves in 60 outings. But he struggled down the stretch, and it carried over into ‘22 with a 4.31 ERA, 3.87 FIP and 1.44 WHIP in 44 games. After returning from right shoulder inflammation last August, however, Barnes posted a 1.59 ERA in his final 24 outings.
